Application mea December s1, 192e. serial No. 688,627.

To all wlwm t may concern.'

Be it known that I, HARRY S. LEVINTHAI'., A

pensing small admeasured j quantities ofv liquid from a bottle and which may be used without moving the bottle. l

A further object is to provide an attach- I ment to a bottle, or other similar container,

for use by druggists'fin preparing prescripf tions and by other dispensers ott-liquids.

A further object is toiprovide a device whereby a very large portion' of the liquid content may be removed therefrom without moving the bottle-from its upright position.

A further object is to provide a reminder.

that the supply of liquid 'is about exhausted before the available supply is entirely gone. Another object is to provide a device for a receptacle that is self closing when not in usel,l making it sanitary andsubstantially air ti t. Y .ther objects and-advantages of the invention will hereinafter appear from a consideration of the following description, when taken in? conjunction with the drawings, wherein y f v Fig. 1 is a vertical central section thru a bottle and the dispenser showing a reciprocatable plunger to compress air in the bottle. Fig. 2'is a modification showing a llexible globe as a means for compressingair.

. i In bothV views the same reference characters are employed to indicate similar p parts.

The dispensing device consists of astop r 5 which may be of glass or other' s uita le material. j In Fig. 1 the stopper is preferably of glass, having a bore 6 communicating with the interior of a bottle 7, at 8. A

. plunger 9 loosely fits the bore so that it may e reciprocated and normally` closes a port 10 in a metal capY 1,1. A spring12 normally' holds the plunger elevated. A stem 13 is secured the plunger-and carriesa thumbpiece `14: on its upper end. i

A pipe 15. the stopper` to a point 16 near m3121919 Qi bottle. The

with which it is pipe 15 is at substantial right angles 'at 17. Its end terminal isvoblique at 18. A

closure 19 overlies the opening 18 to normally close the pipe. I

A pair o'f uprising arms 20 from the cap 11 afford pivotal support for a lever 21 which carries the closure 19 and which is pivoted at v22 between the arms 20. The free end 23 of the lever 21 is slotted and extends about` the stem k13 under the thumb piece 14. A pin 24 under the end 23 lifts the lever to operate the closure when the spring 12 lifts the .plunger 9 and stem 13.

The operation of the device will be clearly understood.

.Pressure on thethumb piece depresses the plunger against the stress of the spring and drives air in the bore 6 into the bottle @t the sameftime the end 23 of lever 21 is depressed andthe outerend of the pipe 15 is simultaneously opened by removal of the closure 19. 'IIhe vintroduction of air under pressure causes displacement of liquid in the pipe 15 ywhich will low out of the end 18 in a smallstream or in .drops depending upon the speed and extent of movement with which 'the plunger is mov When the. plunger'is moved downwardlvY I it opens vent 10 in cap 11 and prevents tendency to formation of a vacuum above the plunger. When the plunger is returned by the spring it closes the vent and'at the same time the closure 19 closes the end 18 of the pipe15.. j

When liquid level in the bottle descends to theend 16 of the pipe 15 it is notice to the di enser that an order for replenishments ould be entered. After this condition has developed an additional quantity of the liquid may be extracted by tilting the bottle, so that the side near the end 16 is lower than the opposite side.

When the device is not in use the bottle is sealed. A

In Fig. 2 the means to compressair 1s the elastic, `compressible globe 9 and the lever 21 has a spoon shape .end 23 overlies the lobe by pressure o thel operators thumb thereon. The cap 11 may be held on th'e stopper-5 by a screw 25 passing thru ears 26, orf otherwise.

The device is valuable because of theease operated and control of the liquid dispensed. Further.

more, the device saves the dangerous necesthe perfectv which l, v and which is depressed sity of lifting and tilting the bottle, an act which causes a large per cent of breakage and `expensive waste of the contents, as the device may be operated by one hand without lifting the bottle from the shelf.

-Having described my invention what I claim as new and desire to secure by Letters Patent, is

A dispensing device comprising acontainer and a separable stopper device having two parallel axially extending bores; an air compressing means associated with one bore to force air into the container; a

pipe extending into the container and thru the other bore in the stopper and deflected laterally from the stopper; a band extending around the outer end of the stopper and clamped thereto providing means to pivotally support a lever and a lever pivoted to said support having one end overlying the outer end of the pipe to normally close the pipe and itsother end extending to the air compressing means.

In testimony whereof I hereunto set my hand.

HARRYS. LEVINTHAL.
